How to build the mesh for 3 injection area within one surface?
2 Attachment(s)
Dear ICEM experts,
I'm trying to build mesh for the burner with 3 injection area in ICEM, the 3 different injection area are in the same surface and shown in the following pictures. There are no further inside structre of it. Could anyone tell me how to build the block for it or give a hint? I also attach the file Attachment 12291 http://www.cfd-online.com/Forums/mem...injection1.jpg http://www.cfd-online.com/Forums/mem...injection2.jpg |
you will mesh the cylinder like normal. nothing really special. then create three different parts (surfaces) so fluent can recognize them as ddifferent boundaries.

here is the little effort made by me. I checked them in fluent and every thing is fine.
I am also uploading 3 parts video on youtube and shall post links in next post. http://imageshack.us/photo/my-images/12/injection1.png/ http://imageshack.us/photo/my-images/69/injection2.png/ |

Ah, some small adjustments are still needed. My primary aim was to clarify the process of creating the o-block and getting different inlets with different boundary conditions in Fluent (Obviously learned from Simon the great http://www.cfd-online.com/Forums/ans...em-fluent.html)
If needed I can rectify these problems and upload new tin and blk files. |
thanks, everyone, especially Far:D. I've build the mesh under Far's instruction, and it turned to be very cool.
The video didn't just help me with this case, but also give me many inspiration about the similar problems. I think it's very good for a beginner like me. By the way, Dear Far, I'm not sure which small adjustments you mentioned, is it important? the quality of mesh I built following your method are all over 0.5, is that OK? |
Actually Ralen is referring to video where the inner most blocks was adjusted. Also he is referring to wrong edge-curve association, which was later corrected in part II (Or part I, I am not sure which part but it is done)

thanks again,Far ! I'll pay attention on the place you mentioned!

I have found one mistake in part I at 3:11 where I have associated four edges to two curves and in reality there were three curves (one is very small).
